list of identifications of the latter's Philippine plants made at Kew. It 

 was originally described from fruiting specimens only, and as the flowers 

 were previously unknown, they are accordingly described here. Flowers 

 white, odorless, in fascicles of from to 10 flowers each, axillary or extra- 

 axillary on the branches below the leaves, the pedicels pubescent, 3 to 6 mm. 

 long. Calyx cup shaped, glabrovis, 5 mm. deep, the lobes broadly ovate, 

 obtuse, about 2 mm. long. Petals linear, obtuse, about 14 mm. long, 

 2.5 mm. wide, fleshy, glabrous, their tips more or less spreading. Fila- 

 ments 8 mm. long, the anthers 3 mm. long. Ovary oblong, 6 mm. long, 

 densely hirsute pubescent, the style glabrous, 4 mm. long. 



Specimens examined, all from Luzon: Province of Bataan, Mount 

 Mariveles (3729 Merrill). January, 1904 (fruit); (6903 Elmer), Novem- 

 ber, 1904 (fruit) ; (2380 Borden) ; (2403 Meyer), January, 1904 (fruit) ; 

 (2794 Meyer), March, 1905 (flower). Province of Benguet, Mount Santo 

 Tomas, (5812. Elmer) , March, 1904 (fruit). 



This species is remarkable for the amount of resin in its leaves, twigs, and 

 fruits; fresh fruits burn readily when a lighted match is applied to them. 



It reaches a height of about 10 m., and is apparently entirely confined to 

 the mossy forests of the higher mountains, being common on exposed ridges 

 on Mount Mariveles above 800 m. 



(4) Pittosporum resinferum, var. orbiculatum var. nov. 



A form apparently identical with the species except that the fruit instead 

 of being oblong, is orbicular or nearly so, 2 to 2.8 cm. in diameter, com- 

 pressed. 



Mount Arayat, Province of Pampanga, Luzon (3919 Merrill), October, 

 1904. Not common, and apparently growing only near the summit of the 

 mountain in the slightly developed mossy forest, at an altitude of 878 m. 

 above the sea. 



Pittosporum ferrugineum Ait.: F.-Vill. Nov. App. 13. 1880. Busaria 

 inennis Blanco, Fl. Filip. ed. 2, 124. 1845: ed. 3. 1:122? 

 No Philippine specimens of Fittosporum ferrugineum Ait. have been seen, 

 although its range is given by King ^ as from Burmah to the Malayan 

 Archipelago, Philippines, and Queensland. F.-Villar refers Busaria iner- 

 mis Blanco here without question, stating that he saw specimens from near 

 Iloilo. Panay. Blanco's specimens were from Calauan, Province of Laguna. 

 Luzon. The fruit of Bursnria inermis is described as being 4-seeded. Avhich 

 at once precludes the possibility of this species being referable to Pittos- 

 porum resinferum or P. odoratum, altliough this character does not conflict 

 with the description of P. ferrugineum.. The description of Bursaria inermis, 

 although very short, applies well to Pittosporum pentandrum, and the 

 species which was seen and described by Azaola, and not by Blanco, might 

 well be identical with Limonia laureola Blanco, of the same \\or\^=^ Pittos- 

 porum pentandrum. Unless fairly typical specimens of Pittosporum ferru- 

 gineum Ait., are found in the Philippines, it will probably be best to refer 

 Bursaria inermis to Pittosporum pentandrum (Blanco) Merrill.
